11-5 TURBOCHARGER LUBRICATION SYSTEM
Pressurized oil is supplied to the turbocharger from the engine. A fitting located in left
crankcase half (2-4-6 cylinder side), below number 2 and 4 cylinder, oil gallery supplies
pressurized engine oil to the turbocharger center housing oil inlet.
Oil is return to the engine from the turbocharger center housing is accomplished by a
scavenge pump contained in the starter adapter assembly.
Flexible, high pressure hoses connect the engines oil system to the turbocharger. Since the
turbocharger is mounted below the center line of the engine, check valves are installed in
the oil supply hose and oil return hose to prevent oil from flooding the turbocharger center
housing when the engine is not operating.
11-6 EXHAUST SYSTEM INSPECTION
50 HOUR INSPECTION - Visually inspect entire exhaust system for security, welded joints
for cracking, evidence of exhaust gas leakage and turbocharger compressor, turbine for
freedom of rotation. Inspect turbocharger oil seals and lubrication system plumbing for
evidence of oil leakage.

except multi-segment "V" band clamps. In the event that exhaust system components have
to be removed, see the L/TSI0-360 Overhaul Manual, Form X30596A.
Stacks, Risers, Elbows - Inspect these components for burned areas, cracks and looseness.
During this inspection give special attention to the condition of welded area and seams for
